first dyno pull

[PxTx]

The SAAC MkI #004 car has the stock 2.5" Borla SS mufflers. Not the best sound test, but it is mild enough to drive daily and loud enough to get attention from traffic around you.

I was told with a blower you need to run a bullet type muffler. I have flows and a off road h pipe I like the sound of the x-pipe better so I'm changing the entire set up. I was thinking slp bullets?

With turbos u need a straight through muffler... Not a blower car... The chambered muffler will cost a turbo big power because of the backpressure involved. Blowers r rpm driven so mufflers won't effect performance as much. I'd do borla xs mufflers... That's what I run on my stang.

Why do you have to run a bullet style muffler? Just wondering. I run a 3 chamber flowmaster catback on my 500 plus rwhp 93 with no issues.

Very well I was mis informed. Thanks for the input guys I will post numbers on Monday. Let's hope for atleast 350rwhp!

 

[teal_93]

x-pipe installed sounds alot better then h-pipe... so just waiting for monday to tune it!

 

[teal_93]

At the dyno now let's hope for 340-350 rwhp

I guess I need to run a cooler plug so it's tuned safe for now until I get the plugs in. And get the mr freeze kit then it's back to the tuner again In a few weeks

 

[PxTx]

Why do you say that? Care to elaborate on how things were going?

I get it that there was some detonation, and colder plugs may be in order, but what kind of boost levels are you trying to tune for?

Do you care to share what the numbers were. Its all in progress. You will get where you want to be.

 

[teal_93]

The car wasn't safe after 5300rpm so it made 305rwhp which makes no sense to me because it made 312rwhp with 24lb injectors and fmu. they told me to get the plugs put themIn and come back they will finish the tune. It had stock motorcraft plugs in it so I got some autolite 23 plugs and gaped them to 33. They also
Suggested the mr freeze kit. So I'm
Ordering that. It makes 9lbs of boost. I should of checked the plugs before I went there. Lesson learned. And also this was in 96 degree heat and humid as heck. It made 305 on the last pull and that was the 14th pull. He said that's why my numbers got
Lower.

 

[91LX713]

Gotcha, I have heard that methanol is a must for peak performance on blower cars so I am sure you will be pleased with the outcome. 96 and 14 pulls had to take its toll.
Good luck and keep us posted.

Ok so I ran into a issue. I went outside today to put the new plugs in and the wouldnt thread into the head (autolite 23)?!!? the orignal motorcraft plugs went in fine. so Im guessing since these are gt40 heads I need a different plug.. so Which plug should I go and get?

 

[WillyB93]

Tell the part store goooru to look in the book/computer for a cross reference to the plug you took out. Or are they the gt40 heads from a newer year, if so just have them look up like a 1996 ford explorer with the 5.0 in it.

 

[teal_93]

No they are stock gt40 heads. I think I tracked down the part# to autolite 104.

 

[WillyB93]

Ok I used to work in a part store so this has happens more then once before!

[teal_93]

Thank you I got the autolite 104

 

[teal_93]

Plugs are in car doesn't break up In higher rpms so back to the tuner next weeknd

 

[WillyB93]

Are you shooting for 400hp plus mark on the car?

 

[teal_93]

400hp would be really nice, but I don't have enough boost/supporting mods. I think with heads and a cam I'd be right at 400. I need to get rid of this blower and either do a turbo or a novi 1000

 

[WillyB93]

I forgot you are running an older blower, well good luck with your new run!
